Hi. I know the most privacy-oriented (and best-working) phone OS is GrapheneOS, but I was wondering about other, less well-known ones, such as VollaOS (modified Android), Sailfish OS or Ubuntu Touch. Are they private? Do they work? Can I run Android applications on them (VollaOS and SailfishOS) without too much effort? I like using Linux, but I rely on many Android apps, such as navigation, mobile banking, the Garmin app, and many others. Do you have any experience with these operating systems?
Yes, but I think Sailfish OS and Ubuntu Touch are Linux-based systems with an Android layer (I don't really know how it works, but it's something like Linux with Android firmware?) so they would work better than the PinePhone. I am interested in people's experiences, and I saw in a video that Android apps run pretty well on Sailfish OS.
